The XLA API retrieves read operations (Select statements)?

Hi all

Firstly, I'm writing a request for implementation of the scheme of replication on databases TimesTen installed on servers that are distributed over several nodes, the application uses the API of XLA for monitors & retrieves changes apply on database TimesTen to a node, then propagates the changes to other nodes.

The application must also propagate the transaction to read for some cases. If the XLA API doesn't get read operations? OTHERWISE, there are solutions to this situation?

Thanks & BR

No, XLA doesn't read operations. XLA is an API 'notification of change '. TimesTen has not any functgionality to allow you to 'hang' selects performed by another connection, sorry.

Put the name of partition in a SELECT statement
Hello

I'm trying to do something like that.

SELECT u.id FROM user PARTITION (SELECT partition_name FROM dba_tab_partitions WHERE table_name = 'users') u u.active = 1 WHERE

The problem is that you cannot have a select in there to retrieve the name of the partition. Is there a way I can do this in a single SELECT statement?

Thanks in advance
Object name cannot be passed to a SQL dynamically. You need to know the name of the object during the compilation of a SQL. If you want to make it dynamic, then use dynamic SQL using EXECUTE IMMEDIATE or DBMS_SQL.

What is the recommended API for reading/analysis of XML in Java files?
Hello, everyone!

In my application, I have to read a XML file. I think that Java has several APIs to parse XML files and as I am new to this, I would like to know from you what is the recommended Java for this API.

Thank you.

Unless you plan to edit nodes and I would recommend that you use a Sax parser, which is a lot less hunger of memory as a DOM parser. The DOM parser to read the entire document in memory for the manipulation of the user.
If you are looking only to read the document and extract specific values then a DOM parser would be an exaggeration. If you are planning leave the document unchanged then a SAX parser is the way to go - a little more complex to write but worth the extra as it will be faster and more scalable.

Use of the TABLE OF... in select statements

Hello

I need to set up a list of objects that require multiple controls and operations in an anonymous pl/sql block. I've created a type that is a table of varchar2 (sys.user_objects.object_name%TYPE).

After a search on the web, I can't understand how to integrate or use this type of table variables.

Here is my code:

DECLARE
   TYPE list_of_objects_t IS TABLE OF sys.user_objects.object_name%TYPE;
   needed_objects list_of_objects_t := list_of_objects_t('OBJ1','OBJ2',...);
BEGIN
   FOR c1_rec IN (
                  SELECT * 
                  FROM   TABLE (
                           needed_objects
                         )
                 )
   LOOP
      DBMS_OUTPUT.PUT_LINE('Ceci est un test');
   END LOOP;
END;
/

It does not work, error are:
PLS-00642 and ORA-22905

How can I make it work?
Thank you
Bruno

You must create a SQL type.

CREATE OR REPLACE TYPE LIST_OF_OBJECTS_T AS TABLE OF VARCHAR2(30);

Example:

SQL> CREATE OR REPLACE TYPE LIST_OF_OBJECTS_T AS TABLE OF VARCHAR2(30);
  2  /

Type created.

SQL> DECLARE
  2     needed_objects list_of_objects_t := list_of_objects_t('OBJ1','OBJ2');
  3  BEGIN
  4     FOR c1_rec IN (
  5                    SELECT *
  6                    FROM   TABLE (
  7                             needed_objects
  8                           )
  9                   )
 10     LOOP
 11        DBMS_OUTPUT.PUT_LINE('Ceci est un test');
 12     END LOOP;
 13  END;
 14  /
Ceci est un test

- but the condition is that I list all types of event in the search list
-with a total number of events by event type for each month in a number of calendar months (user will select months like August 2012 or a range of month August 2012 - October 2012)
-the query above just list all the events (see table engagement_event) that have the date_join_court and date_terminated meets the required conditions.
-I wonder, is it possible to enumerate all types of event, then monthly for each event type with the total as

Please give sample data and expected results.

Hope below is what you'd expect - yet, I would like to ask a clarification - you have a filter 'where active = 1.
And yet, you want these types in the output. I commented on this to my query filter.
You can change accordingly

)

How to get the name of the adapter file file (read operation)
Hi all

I like to read files from the local site, I gave the filename property in the jca file = *. * (who reads all the files) and now I want to read the name of the incoming within bpel file and I want to copy the file name in a variable. Is this possible?
Yes, its possible.
In your business, set below property in its properties tab:

Before this make sure you create a variable of type string "filename".
Whatever your file adapter reads, his name will be stored in this variable.

I hope this helps.

Kind regards

TimesTen create a lock for a select statement through sqldev

What ttisql use connect to TimesTen Release 7.0.6.15.0 to autocommit = 1, there is no lock for a select statement.
but when I use sql developer (driver is ttjdbc5.jar, regardless of the version) to connect, even with autocommit = 1, there will be locks for the select statement.
Is this a bug? How can I achieve the same no lock for a select statement through sql developer? Thank you.

-your update told me that you are connected to a remote timesten data store using the client driver

-the output from ttXactAdmin shows that SqlNavigator has a shared lock on the database itself: it will not interfere with someone else "read operations and I think that until you actually try a kind of DML against the database that e IX lock on the database lock will not interfere with any other DML either."

-sharing database lock is still acquired for any transaction TimesTen. You can test it for yourself ttisql: set off autocommit, perform a simple update and do not commit the transaction. Then, open a separate session and run ttxactadmin - you will have the database IX lock as well as the various locks on the tables and indexes.

-I think this pretty much proves my original thought: this sqlDeveloper attaches to TimesTen in transaction mode. However, the IX lock on the database will not interfere with anyone else's work and should not be a problem.

Ask about the ReadConsoleW API

Hello, I have a cople of applications below concerning the API ReadConsoleW:
(1) I use the ReadConsoleW API to read all the console buffer both its working fine in all windows except Windows 2000 and Windows XP 64-bit OS.

(2) and if I use the ReadConsoleW API to read the console buffer of a character at the same time, the problem is its fine if I give input keyboard, but when I copy and paste my couple of lines of text to console am adding an extra character of work ' at the beginning of each new line. find the code example below.

uint dummy_errors;
u16buf static wchar_t [MAX_CONSOLE_LINE_SIZE + 1], * pos;
size_t mblen = 0;
DWORD console_mode;
DWORD nchars;
Console handle = GetStdHandle (STD_INPUT_HANDLE);
(Mbbufsize > 0) DBUG_ASSERT; / * Need space to the coarser '\0 ' * /.

GetConsoleMode (console, & console_mode);
SetConsoleMode (console, ENABLE_LINE_INPUT |) ENABLE_PROCESSED_INPUT | ENABLE_ECHO_INPUT);

for (pos = u16buf; pos)< &u16buf[max_console_line_size]="" ;="">
{

DWORD nchars;
If (!.) ReadConsoleW (console, pos, 1, & nchars, NULL). nChars == 0)
{SetConsoleMode (console, console_mode); return null; }
If (* pos == L '\r') / * do not '\r' in the resulting string, pop it * /.
continue;
If (* pos == L '\n')
break;
PDS ++;
}

Formatting for a select statement
I am trying to include formatting in a select statement.

The data, I'm pulling compared to the SSN for a unique value. The problem is that the SSN is formatted with dashes in a table and not in the other.

Example:

Table 1
Name SSN
John 400-30-8745
Mary 348-00-4093

Table 2
Name SSN
John 400308745
Mary 348004093

What I would do is:

Select * into Table1, Table2 where table1.ssn = table2.ssn

However, I am unable to do so due to the formatting.

Thxs!
It will not replace the data in the database because it is a SELECT statement and not a DML (INSERT, UPDATE, DELETE) statement. You can also consider putting a function based on this column in table1 index to facilitate this request. However, it depends on many factors and because we do not know the versions, estimated use, how many times the table is updated, etc., we can say with certainty whether this can help or not. An example would be:
```
CREATE INDEX TABLE1_SSN_FBIDX ON TABLE1(REPLACE(SSN,'-'))
```

to find the number of records retrieved in the select statement in the cursor
Hi all
with the cursor, I'm selecting select statement together and writing in the .txt file.
his worksheet, but it should not open the file, if the cursor returns nothing.
How to find the number of records returned by the select statement in the cursor.
pls help me.

Thank you...
Don't understand what you're trying to say, but maybe it's...
```
DECLARE
   vCounter NUMBER;
   -- Other variables...
BEGIN
   vCounter:=0;
   FOR .. IN cursor LOOP
    IF vCounter=0 THEN
      -- Here open file...
      -- Here write one time data...
    END IF;
    -- Here write cursor data...
    vCounter:=1;

DDL lock on the object in a SELECT statement?

Environment:
Oracle 11.2.0.4 EE on Solaris
My client called me when she was trying to create a new index on a table and the process was just hanging. Also, she was not able to DELETE an existing index on the same table, which deal with hang them as well.
After reviewing the advice DBA_DDL_LOCKS, I found a DDL lock on the target of the index table.
The DDL lock is held by a process doing a SELECT on the table and this process worked for several hours.
There was no entry in V$ LOCKED_OBJECTS for the table.
I don't know, yet, what other operations prior to the SELECT statement in the offending process, I have not heard of the user yet.
I realize a DDL lock is placed on objects to prevent changes while specific operations are directed against this object, i.e. the DROP, UPDATE, compile the PACKAGE, etc.
Question: Is a select also place a DDL lock on a table at a level that would avoid a new index is created or an existing index having fallen?
Thank you very much for your comments!
Any reference to the resolution is greatly appreciated.
I searched some Concepts Developers Guide, SQL, even Google reference Guide.

> My question is now, this lock persists for the duration of the running query?

Easy enough to show that it is not.

Session1:
```
SQL> create table foo(bar number);     

Table created.                         

SQL> insert into foo values(1);       

1 row created.                         

SQL> commit;                           

Commit complete.                       

SQL> variable x refcursor
SQL> variable a number
SQL> begin
  2  open :X for select bar from foo;
  3  end;
  4  /                                 

PL/SQL procedure successfully completed.
```
Session 2:
```
SQL> drop table foo;

Table dropped.     
```
Note that I was able to remove the table even if select is still 'in progress' - the cursor is open.

If you really want to blow your mind, go back to the session 1:
```
SQL> begin
  2  fetch :X into :a;
  3  end;
  4  /                                

PL/SQL procedure successfully completed.

```
The picture has gone, but I can always look for him. However, try again:
```
SQL> /

ORA-00604: error occurred at recursive SQL level 1
ORA-00942: table or view does not exist          
```
Note that the forum software is stupid. is: followed by x. seems it's really important to have a smiley to lovey eyes in a technical forum.

Edit - and when you format the SQL code, it is removed completely and render invisible... silly.

I edited my code to use: X and the problem disappeared...

Can I change the query1 query for plan2?

As Juliet was mentioned in the first SQL that you generate from the ENAME list that you must pass in the IN clause when executing. But in the second SQL, it passed as a static value. So first SQL must do more work. So you see a different execution plan.

But this is a work around to get what you are looking for. But I can't say it's a foolproof method. But anyway here you go.

Menu Module v2 supported for the selected state?

I can't understand if v2 menu module supports the selected state. I remember reading somewhere that it was planned to produce in the future, but it seems that the file /ModuleTemplates/Menu/Default/container.html has accommodations for her.
A resource if so, it would be appreciated.

By default I did, the JavaScript code is there in the updates page and not different from the normal version in this respect.

The XLA API retrieves read operations (Select statements)?
